rkindig Posted June 7, 2020 Share Posted June 7, 2020 I updated the U1MB in my 800XL to 3.1 with no problem. Then... I tried updating the firmware on my SIDE2 cart to 3.1 as well and now the machine seems bricked. Screen comes up but stays at blue screen. I think I might have updated the U1MB firmware with the SIDE2 image. How can I fix this? thanks. Randy Quote Link to comment Share on other sites More sharing options...

If you send me the EPROM chip, I can flash it and test on my U1MB and return to you. PM me if you need any help. Quote Link to comment Share on other sites More sharing options...

Much appreciated. I contacted FlashJazzCat and he's sending me a properly programmed chip. Terrific guy! 1 Quote Link to comment Share on other sites More sharing options...
